The noise complaints are numerous. So why doesn't Spondoolies address this issue and make an alternate version in a 2U rack size? I'm sure they would sell more units if they weren't so loud.
Because the product is already obsolete and they have the SP 30 to move now. Wouldn't make sense spending the money on engineering for something that is soon to go EOL. Would be a great miner though.
Spondoolie is making another batch of SP10's for sale in mid June. While it is obsolete for some people, it isn't obsolete for everyone. But at that point in time it is more worth it to buy an SP30. 1.4TH/s is just a smudge these days. I'm even thinking of getting an SP30 but told myself I would never pre-order another miner in my life and I'm sticking to that. We could have $200 BTC prices again over night.
